[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be an intermediate component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] refer to Figure 1 and Figure 2 In one embodiment of the present application, a rework table with adjustable angle is disclosed, which includes, from bottom to top, a base 1, a first adjusting member 2, a second adjusting member 3, and a workbench 5.

[0033] The base 1 is provided with two upright posts 11 , which are vertically connected to the base 1 , and one end of the upright posts 11 away from the base 1 is used to connect to the first adjusting member 2 .

[0034] Furthermore, the two columns 11 are arranged facing each other, and both ends of the first adjusting member 2 are hinged to one column 11 to form a pivot for its own rotation, so that the first adjusting member 2 can rotate around the hinge.

[0035] refer to Figure 2 and Figure 3 The second adjusting member 3 has a fixed portion 31 and a movable portion 32 relative to each other, and the fixed portion 31 and the movable portion 32 are rotatably connected. The fixed portion 31 is connected to the first adjusting member 2, and the movable portion 32 is connected to the workbench 5.

[0036] In some embodiments, the workbench 5 is arranged in a horizontal direction, the upper end surface of the workbench 5 is used to place and fix the workpiece, and the lower end surface is connected to the movable part 32.

[0037] Furthermore, the second adjusting member 3 is used to make the workbench 5 rotate within its own plane, and the first adjusting member 2 drives the second adjusting member 3 and the workbench 5 to rotate around the pivot, changing the plane of the workbench 5 to achieve angle adjustment of the workpiece on the workbench 5.

[0038] refer to Figure 2 In order to make the adjustment of the first adjusting member 2 controllable, the first adjusting member 2 needs to be fixed after it is rotated to an appropriate angle. In some embodiments, a locking mechanism 4 that cooperates with each other is provided between the end of the first adjusting member 2 and the column 11 to limit the relative movement between the first adjusting member 2 and the column 11.

[0039] Furthermore, the locking mechanism 4 includes a locking member 41 and a movable groove 42. The locking member 41 is connected to the first adjusting member 2 and moves synchronously with the first adjusting member 2; the movable groove 42 is provided on the column 11, one end of the locking member 41 passes through the movable groove 42 and is connected to the first adjusting member 2, and the other end of the locking member 41 acts on the side wall of the column 11. The movable groove 42 is provided along the movement path of the locking member 41. When the first adjusting member 2 rotates, the locking member 41 moves in the movable groove 42. When the locking member 41 approaches the first adjusting member 2, static friction is generated between the locking member 41 and the side wall of the column 11, interfering with the rotation of the first adjusting member 2, forming a locked state; when the locking member 41 moves away from the first adjusting member 2, the movement interference between the locking member 41 and the side wall of the column 11 is eliminated, forming an unlocked state.

[0040] refer to Figure 4 In some embodiments, the workbench 5 fixes the workpiece by adsorption.

[0041] A negative pressure is formed at the upper end surface of the worktable 5 in contact with the workpiece, so that the workpiece is adsorbed on the worktable 5. In this way, the workpiece is fixed more quickly and the size of the workpiece that can be adapted is increased.

[0042] Further, the worktable 5 is provided with an air flow channel 51 and a vacuum suction port 52. One end of the air flow channel 51 is in communication with the upper end surface of the worktable 5, and the other end is in communication with the vacuum suction port 52. A negative pressure is formed at the upper end surface of the worktable 5 by vacuum suction at the vacuum suction port 52.

[0043] Further, to ensure the stability of the workpiece adsorbed and fixed on the worktable 5, in some embodiments, the upper end surface of the worktable 5 is provided with a plurality of flow guide grooves 53, the air flow channel 51 is in communication with the flow guide grooves 53, and the plurality of flow guide grooves 53 are distributed in a cross pattern to form a mesh structure. A sealing strip 54 is arranged on the outer periphery of the mesh structure. The mesh structure increases the area of the negative pressure formed and increases the contact surface with the workpiece, and the sealing strip 54 arranged on the outer periphery of the mesh structure ensures the effectiveness of the negative pressure.

[0044] Reference Figure 6 To further ensure that the negative pressure uniformly acts on the contact surface of the workpiece, in some embodiments, a plurality of air flow channels 51 can be arranged in the mesh structure formed by the flow guide grooves 53.

[0045] The worktable 5 includes a first table surface 55 and a second table surface 56 that overlap each other, and a vacuum suction cavity 57 is arranged between the first table surface 55 and the second table surface 56. A plurality of air flow channels 51 are arranged on the first table surface 55, one end of each air flow channel 51 is in communication with the vacuum suction cavity 57, and the other end is in communication with the flow guide groove 53, so that each air flow channel 51 can have an effective vacuum suction effect.

[0046] At the same time, the vacuum suction port 52 is arranged on the second table surface 56 and is in communication with the vacuum suction cavity 57.

[0047] In combination Figure 2 With Figure 5 In some embodiments, to avoid the external vacuum suction pipeline from being wound when the worktable 5 rotates with the second adjusting member 3, the vacuum suction port 52 and the rotation center of the second adjusting member 3 are coaxially arranged.

[0048] Further, a negative pressure channel 33 is arranged in the second adjusting member 3 along the axis, one end of the negative pressure channel 33 is in communication with the vacuum suction cavity 57 through a through hole 59 on the second table surface 56, and the other end is connected to the vacuum suction port 52.

[0049] Further, the second table surface 56 and the movable part 32 are connected by a flange structure 58, and a sealing ring is arranged at the connection between the negative pressure channel 33 and the through hole 59 for sealing.

[0050] This application is used for polishing and repairing computer shells, and can be angled and rotated; it uses vacuum adsorption,

[0051] It can reduce the number of jigs used and avoid the jig shaking during the rework process without vacuum adsorption, which may cause damage to the workpiece cavity. This improves the yield rate, reduces the cost of jig production, reduces the number of product pick-up and placement, and reduces the labor cost of rework.

[0052] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they should be considered to be within the scope of this specification.
